I have just recently glanced across some of the code and noticed that most if not all exceptions in the Jnode code have been thrown. My thoughts were that you could code a custom bug tracker that will tell what application was run and then when an exception is caught send it to a mysql database possibly on this server? As I can see so far the implementation of this will be fairly easy. It could even be possible to create a randomized hash for each persons machine that could be updated as bugs come across for further fully featured bug tracking.
